Abstract

In this work, a new experimental method based on IR thermography, has been developed to improve the precision of mass measurements in order to obtain as well as possible the influence magnitudes that distort the real mass of the mass standards when the balance is used. With this method it is possible to quantify the drag-froces values present on surroundings of the measure. The work reveals that the drag-forces are important and it is necessary to take them in account in the mass real determination. Depending on the shape, material, environmental conditions but the drag forces change not all the variables contribute in the same order of magnitude.
